[PATCH] D35462: Also add the option -no-pie (like -nopie)

[Sylvestre Ledru via Phabricator via cfe-commits]

sylvestre.ledru created this revision.

For example, this option is expected by ghc (haskell compiler). Currently, building with ghc will fail with:

  clang: error: unknown argument: '-no-pie'
  `gcc' failed in phase `Linker'. (Exit code: 1)
  . /usr/share/haskell-devscripts/Dh_Haskell.sh && \
  configure_recipe

This won't do anything (but won't fail with an error)
